Thanks. I had the same issue. I would suggest these lines become a part of the standard global.conf. I'm guessing the problem doesn't show up for those who load both the File Problems and Database Problems. I'm trying to stick to just Database.
I suppose I had this problem before, but just ignored the errors since there were plenty of Calc I and II problems. Now that I'm doing Calc III for the first time and Union seems to have the biggest collection, I needed this fix.
